OSCAR DREY, OF MANCHESTER, ENGLAND.

WEFT-PILE-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent NO. 650,969, dated June 5, 1900. Application filed July 26,1899. Serial No. 725,160. (No model.)

To all whom it may concern:

Be it known that I, OSCAR DREY, a citizen of the British Empire, residing at Manchester, in the county of Lancaster, England, have invented certain new and-useful Improvements in Weft-Pile-Qutting Machines, of which the following is a full,clear,and exact description.

This invention relates to machines in which floated weft-threads on woven fabrics are cut so as to produce pile fabrics.

In the type of machine to which this invention particularly relates the two ends of the cloth are joined together and the thus-produced endless fabric is caused to travel continuously through the machine. In one part of its passage, where it is in a horizontal open condition, the weft-floats are out by a suitable knife, which may either be attached by its holder to the machine or be held by the operative. From the cutting-point in the upper part of the machine the fabric passes to and is folded in the lower part, where the folds of the fabric are reversed in such a manner that the folds first made may be first unfolded without interfering with folds made afterward. The unfolded cloth returns to the cutting-point through stavin g and tension devices, and each time that the junction between the two ends of the cloth is reached the attendant shifts the knife to recommence cutting the pile in another race.

My presentimprovements relate to the folding mechanisms of such machines, and have for their object to simplify their construction and to render them more certain in action.

I will describe the improvements with reference to the accompanyingdrawings,in which Figure 1 shows a vertical longitudinal section through the machine, the driving mechanism being omitted. Fig. 2 shows a plan of the complete machine; Fig. 3, a partial sectional side view on a larger scale; Fig. 4, a partial cross-section; Fig. 5, a partial side view; Fig. 6, an end view of the lattice-driving gear; Fig. 7, a diagram showing the arrangement of the folds of cloth in reversing; Fig. 8, an elevation of one of the two arms of the folder as seen from within the machine and drawn to a larger scale; and Figs. 9 and 10, respectively, side and end elevations of the fold-beater.

In each of the figures, where the parts are represented, 1 indicates the framing of the machine, and 2 the woven fabric upon which the floated weft is cut to form the pile. These shaft 5 has also fixed upon it a wheel 13, gearing with the wheel 14, fixed u pon the shaft 15. The shaft 9 also has fixed upon it the wheel 16, gearing with the wheel 17, fixed upon the shaft 15. This latter shaft will consequently be driven in one or the other direction, according as it is driven from the shaft 5 or from the shaft 9. By this arrangement if the machine be driven from the shaft 9 for reversing it will be seen, following the shown ratios of gearing or thereabout, that it will be driven more slowly than in the normal forward direction by the shaft 5. The shaft 15 carries the drawing roller or drum 18 and the Wheel 19, which gears with the pinion 20, fixed upon the roller-shaft 21.

Near the top, at the front end of the machine, there is mounted the guideroller 22,

around which the cloth passes from the cutting-point to the drawing-roller 18, whence it travels around the roller 21 to the roller 23, on the spindle of which or near thereto there are mounted the two swing-arms 24 and 25, one of which is separately shown drawn to a lar erscaleb Fi .8. These endulum-arms a b carry at their lower ends the parallel rollers 26 and 27, between which the cloth passes just 1 before it is folded by the motion of the arms.

These rollers are driven, as shown by Figs. 2, 3, and 4, bya belt 28 from the pulley 29 on the shaft 15. This belt compels therotation of the pulley 30, fixed upon the spindle 23, upon which there is fixed the contiguous and similar pulley 31. On the spindle of the roller 27 there is fixed a pulley 32, which is driven from the pulley 3l by the second belt 33. The two rollers 26 and 27 are geared to gether by the wheels 34 and 35, Fig. 2. The

journals of the roller 26 are carried in slotbearings, as shown by Fig. 8, in which slots their movement in one direction is limited by the ends of the levers 36, each of which is adjustable by a screw 37. This adjustment is regulated according to the character of the cloth operated on in the machine. Movement of the journal and roller in the otherdirection is possible, but is restrained by the arm 38 and spring 39, and thus a limited amount of elasticity is provided.

The fabric 2 passes from the roller 23 downward between the rollers 26 and 27. A pendulum motion is given to the swing-arms and rollers by means of the connecting-rod 40 and the lever t1, which at about one-third of its height from the fulcrum 48 carries a friction-bowl in the grooved cam ti on the shaft 43. The motion of the pendulum and the rotation of the rollers 26 and 27 cause the fabric to be delivered in folds upon a triangular arrangement. of rollers or staves t4, Figs. 1, 3, and 7.

To prevent ballooning of the cloth during the plaiting or folding, there is attached toa stayrod, which connects the two pend ulumarms, a beater .45, which pats down each justmade fold. This heater is separately shown in end and front elevation by Figs. 9 and 10.

Just below the slaves it there is a drum 46. Referring to Figs. 1 and 3, it is seen that as the folds of cloth are produced their edges fall to the rightand to the left of the triangle formed by the staves ti and in superposition with the drum 46, which turns in the direction indicated by the arrow, Fig. 1. Looking at the diagram, Fig. 7, which indicates in section the arrangementof the folds of cloth in reversing, it is apparent that the apparatus lays the more recently made folds over the slaves ll, whence they pass under the drum. ()ver the staves the folds last made are neeessarily uppermost and outermost; but the motion of the drum and lattice is continually pulling the accumulated folds in the direction of the arrow and drawing them under the drum. \Vhen they arrive in this position, the folds f which over the staves are uppermost are lowest and come in contact with the lattice. It follows that the earliermade folds a must be uppermost on the lattice and the later-made folds f must be below them. It is advantageous that the motion of the drum and lattice 6- should be intermittent. This motion may be produced by the means illustrated by Figs. 3 and t. A cam -17 is fixed on the shaft 43, which is rotated, by means of the wheels 17 and 49, from the shaft 15. The cam actuates a lever 50, which is connected by a link'to the lever 51, on which there is an arm 52, carrying the click 53, which engages the teeth of the ratchet-wheel 54, fixed on the shaft 55. On this shaft there is also fixed a spur-wheel 56, gearing with the intermediate wheel 57, meshed with the wheel 58, fixed on the shaft of the wheel 59, which gears with the wheel of the drum 4G. The drum is thus intermittently rotated according to the contour of the cam 47. A second pinion 61 is also fixed upon the shaft at the back of the machine and gears with the wheel 62, which drives the wheel 63, fixed upon the spindle of the roller 63, which partly carries and gives motion to the endless lattice 64. This lattice passes under the drum 46 and returns around the rollers 66 and 65, of'whieh G6 is adjustable in such a manner that by its adjustment the tension of the lattice is regulated. Backward motion of the lattice system may be prevented by means of a click 67 engaging with the teeth of one of the gearing-wheels or, as shown, with the teeth of an additional ratchet-wheel 68- on the shaft 55, Figs. 2, 3, and 6. By the motion of the drum 46, as already hereinbefore described, the folds of cloth are carried down to the lattice, upon which they are reversed and by which theyare conveyed to the point where the cloth is unfolded, and whence it passes over the suspended roller 69, around thestaves or rollers 70, around the adjustable roller 71 and roller 72, the tension-rollers 72} 7t 75 7t) 77 7S, and the guide-rollers 7!) and 80, whence it returns to the cutting-point.

Those parts of the machine hereinbefore described which do notrelate to the mechanisms and parts hereinafter claimed form the subject-matter of an application for Letters latent, Serial No. 717,270, filed the 18th of May, 1809.

Having now particularly described my said invention, I declare that what I claim is 1. In a weft-pile-cutting machine, the combination and arrangement with the two rollers of the pendulum mechanism, of fixed bearings in the two swing-arms for one of the rollers, and slot-bearings for the journals of the other roller, an adjustable stop to prevent the motion of each journal in one direction anda spring-controlled stop restraining the motion of each journal in the other direction, substantially as described.

2. In a weft-pile-eutting machine, the combination with the two swing-arms of the pendulum-folding mechanism, of slotted bearings for the journals of one of the rollers, and adjustable stops preventing the motion of each journal in one direction and spring-stops restraining the motion of each journal in the other direction, substantially as hereinbefore described.

In witness whereof I subscribe my signature in presence of two witnesses.
